SPECIFICATION forming part of Letters Patent No. 649,808, dated May 15,1900 Application filed February 14, 1900. Serial No. 5,217. (No model.)

To (LZZ whont if; may concern.-

Be it known that I, l\IICHAEL BYs'rnoM, a citizen of the United States,residing at Centreville, in the county of Turner and State of SouthDakota, have invented a new and Improved Plow, of which the following isa full, clear, and exact description.

One purpose of the invention is to construct an easy-running plow havinga fingered moldboard and means for quickly and conveniently adjustingthe fingers of the moldboard, so that any undesirable material upon thefieldsnch as weeds, long stubble, straw, &c.-may be covered up whetherthe ground he loose and dry or wet.

Another purpose of the invention is to so construct the plowshare thatit will produce a straight well-defined cut and the point will remainsharp for a long time and so that the landside will be subjected to butlittle pres sure and the share will scour itself and be kept clean inalmost any kind of soil.

The invention consists in the novel construction and .combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a plow constructed in accordance withmy invention. Fig. 2 is an enlarged perspective view of the rear portionof the plow, parts being in section. Fig. is a vertical section througha portion of the said plow, particularly through the moldboard; and Fig.4 is a perspective View of the moldboard and landside, illustrating themanner in which they join, the fingers of the moldboard being brokenoff.

A represents the beam of the plow; B, the handles; C, the landside, andD the moldboard. The moldboard is made in two sections-a loweruninterrupted or comparatively-straight blade-section 10 and an upperfinger-section, the fingers 13 of which section are of any desirednumber. The blade section 10 of the moldboard at one end is carrieddownward vertically at a right angle to the body, forming the forwardportion 11 of the landside C and likewise a portion of the point of theplowshare, which point is also partially formed by enlarging the bladesection 10 of the moldboard at the downwardly-extending member 11, sothat a de cided and well-defined point 12 is obtained. The fingers 13are at any suitable distance apart, and these fingers follow thecurvature of the blade-section 10 and are at more or less of a rearwardinclination. The fingers at their lower ends abut against the up peredge of the blade-section 10 of the moldboard, as shown in Figs. 1 and.4, and are adjnstably attached, preferably, to extensions l-t from aplate 15, which is secured in any suitable or approved manner to theunder face of the blade-section of the moldboard, as shown best in Fig.2. Usually the connection between the fingers 13 and the projections 14is made through the medium of bolts 14:, passed through both parts, saidbolts bcing provided with suitable nuts, and in order that the fingersmay be adjusted to or from the rear of the plow each finger is providedwith a single opening, through which a bolt 14 is passed, while theprojections 14 from the supporting-plate 15 are provided with twoapertures 16, in to either one of which the said bolts 1% may enter. Inthis manner the various fingers may be brought closer together orcarried farther apart, as the character of the soil may demand.

The landside C may be made of one or more pieces, but is usuallyconstructed of a single piece of metal, and the forward end of thelandside abuts against the rear end of the downwardly-bent member 11 ofthe bladesection of the moldboard, as shown in Fig. 4-, and the landsideis attached to the blade-section 10 of the inoldboard D through the1nodium of a frog 18 of any desired construction.

The left-hand handle is attached to the ill-- ner face of the landsideor to the inner face of the frog 18 and to the beam A of the plow, whilethe right-hand handle is attached to the right-hand member of asubstantially V- shaped bracket 19, which bracket is secured upon across-bar 20, extending from the land side to the blade-section of themoldboard at or near the rear portion of these two parts. An uppercross-bar 21 is usually attached to the 1eft-hand handle and to abracket 22, which extends downward from the right-hand handle, and thesaid cross-bar 21 loosely rethe lower bolts 14: of the moldboard areloosened the fingers may be given any desired sidewise inclination bysuitably adjusting the nuts 24.

It is evident from the foregoing description that the fingers of themoldboard are not only capable of adjustment in a forward and rearwarddirection, but may be given any desired adjustment to or from the outerface of the blade-section 10 of the moldboard.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a plow, a moldboard comprising a lowerblade-section having an integral point, a portion of the blade-sectionextending downward at an angle to the body, forming a portion of thelandside and a portion of the point of the plowshare, and fingersadjustably connected with the blade-section of the said moldboard, so asto be brought closer together or carried farther apart, which fingersfollow the curvature of the moldboard and have rearward inclination, andmeans for sidewise adjustment of the said fingers, as specified.

2. In a plow, the combination, with a landside, of a moldboardconsisting of a lower blade-section provided with an integral point andhaving one end turned downward to form a continuation of the landside atthe'point, and a series of fingers extending from the upper edge of theblade-section of the moldboard, which fingers follow the curvature ofthe blade-section, means whereby the fingers may be adjusted toward andfrom each other, a cross-bar located adjacent to the convexed surfacesof the fingers, and adjusting-bolts carried by the said cross-bar andconnected one with each finger, whereby the fingers may have sidewiseadjustment, for the purpose set forth.

3. In a plow, a moldboard comprising a share-section and a series ofcurved fingers extending from the upper edge of the share- .section,said fingers being adjustable toward and from each other, and also tovary the sidewise inclination thereof, as set forth.

4. In a plow, the combination with the share-section of a moldboard, ofcurved fin gers having their lower ends adjustably connected with theshare-section, a cross-bar carried by the share-section in rear of thefingers, and bolts connecting the fingers with the cross-bar,substantially as described.

5. In a plow, the combination with the share-section of a moldboard,"and the landside, of a plate secured to the rear of the sharesectionand provided with extensions projecting above the upper edge of thesame, curved fingers secured to said extensions, a bar secured to thelandside and to the plate of the share-section, a bracket carried by thesaid bar, a cross-bar carried by the bracket, and bolts connecting thefingers with the crossbar, substantially as described.

6. In a plow, the combination with a mold-.

board formed of a share-section, and a fingersection, the fingers ofwhich are curved and extend from the upper edge of the share-section,the landside, and a beam secured to the landside, of a bracket supportedat the rear of the share-section, a cross-bar secured to the bracket,bolts connecting the fingers with the cross-bar, and handles, one ofwhich is secured to the landside and to the beam and the other to thebracket and connected with the cross-bar by a brace, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MICHAEL BYSTROM.
